I was an early adopter of Oura, and have recently stopped wearing it. I've reverted to the Apple Watch & EightSleep for all of the tracking I could ever need. I found the experience with Oura to be overly optimistic numbers wise, as well as borderline dark patterns in the app to drive my anxiety around getting good scores.
How has all your data changed your sleep and do you think you could have made changes without that data?
